地球是我们赖以生存的家园,它就像母亲一样,为我们提供着生存的资源和条件。我们是地球的主人,我们要像善待自己一样去保护它。 谁不想让自己的家园变得更美好,更漂亮?然而,随着科学技术的发展,各种五花八门的生活垃圾越来越多,其中大多数垃圾都是会造成环境污染的。比如说我们常用的电池,如果用完后不进行适当的处理,那么将会造成极大的环境污染。据研究,一节废的纽扣电池能使60万升的水不能饮用。如果每人丢弃一颗废电池,那么到了那时,水,将成为奢侈品。 所以,为了保护环境,请将垃圾分类。 我国于2008年6月1日起实行“限塑令”,这一做法,使我国每年节省三千七百万桶石油。塑料袋,这种东西对于普通家庭来说再普通不过了,可是你知道吗,塑料袋却是污染环境的一大因素。塑料袋以石油为原料,不仅消耗了大量资源,而且还需要500年的时间才能被自然分解。 所以,为了保护环境,请减少使用塑料袋。最近在哥本哈根召开的全球气候变化大会使我们再一次敲响了警钟。虽然最终未能达到预定的效果,但是如果我们没有做到,开再大的会议也只是形同虚设。会议上说,现在全球平均气温正逐渐升高,大部分冰山已经开始融化。如果再这样下去,那么世界将被水淹没。现在的全球平均气温较以前已经升高了1℃,别看只是小小的1℃,可这是“全球平均气温”啊!如果全球平均气温升高4℃,那么北极和南极的气温将升高16℃,到那时,北极和南极也可以看到大树了。你想一想,到那时,世界将会成为什么样?其实导致这些灾难的罪魁祸首就是我们人类。据研究,我们每天使用的电器或其他东西会排放大量的二氧化碳,而二氧化碳却是使气温升高的一大因素。如果减少使用电器,那么二氧化碳的排放量也会随之减少。汽车尾气中也含有大量的二氧化碳,应随时提醒爸爸妈妈上班或外出旅游时,应乘坐地铁或公共汽车,尽量少开私家车,这样能减少大量二氧化碳的排放。所以,为了保护环境,请减少使用电器,少开私家车上班或旅行。 作为社会的主人,改善地球环境,是我们义不容辞的责任和义务。如果世界人人环保、天天环保,就可以创造一个崭新、美丽的世界!

The simplest water pollution definition would be any contamination of water bodies with some pollutant(s) that changes physical, biological, and chemical conditions of any body of water making this water harmful for environment and surrounding Water pollution occurs once too much pollutants (mostly in form of different waste) are discharged directly or indirectly into water Water pollution does not only cause great environmental damage but is also the leading worldwide cause of deaths and diseases responsible for the deaths of more than 14,000 people each day, mostly in developing Many people are not aware that water pollution is serious problem in almost all parts of the world, and not just in third world countries like some choose to In fact many experts will tell you that reality is completely different than the common belief, and that actually water pollution problem is already out of Water pollution problem is in most cases connected with the careless handling of chemical agents, toxins introduced into our water through industrial dumping, and farm All these factors make our water unsafe to For instance, the chlorine that is widely used to disinfect our water is believed by many to be carcinogenic, and therefore a major health issue that significantly contributed to worldwide rise of cancer Basically chlorine is present in every glass of water we draw from our tap, and although some studies have confirmed that chlorine can indeed be one of the cancer risk factors we simply cannot do without it because by removing chlorine from our water we would open the door to many waterborne diseases that would kill millions of people around the So how to protect yourself from water pollution? The best option available to us is to install a multi-layered home water filtering system in your The best option is multi media block system that has an activated granular carbon filter, a sub micron filter, and an ion This system is capable to prevent up to 99% of all of the harmful contaminants present in our water from entering your High quality home water filtering system is really your best ally against water 网上找的这篇,符合你的基本要求了,希望能帮到你。
